Setting up pcap Overview
Because the pcap data source creates an Apache Storm topology that can rapidly ingest raw data directly into HDFS from Apache Kafka, you can store all of your cybersecurity data in its raw form in HDFS and review or query it at a later date.
The pycapa tool, for low-volume packet capture
The Fastcapa tool, or high-volume packet capture
Fastcapa is a probe that performs fast network packet capture by leveraging Linux kernel-bypass and user space networking technology. The probe will bind to a network interface, capture network packets, and send the raw packet data to Kafka. This provides a scalable mechanism for ingesting high-volumes of network packet data into a Hadoop cluster.
Fastcapa leverages the Data Plane Development Kit (DPDK). DPDK is a set of libraries and drivers to perform fast packet processing in Linux user space.
